Note: This chart simplifies a highly complex topic for patients’ informational use. The effective doses are typical values for an average-sized adult. The actual dose can vary substantially, depending on a person’s size as well as on differences in imaging practices.
The scientific unit of measurement for whole body radiation dose, called "effective dose," is the millisievert (mSv). Other radiation dose measurement units include rad, rem, roentgen, sievert, and gray.
Radiation Doses for Common CT Scans. Common types of CT scans and the amount of radiation you would absorb from them include: Belly and pelvis: 10 mSv, equal to about 3 years of background...
This dose tracking software can identify outliers for your entire CT fleet by scanner and examination type. By setting alerts if radiation dose thresholds are exceeded, quality metrics can be maintained in a retrospective fashion.
29 Απρ 2022 · The radiation dose sheet (hereafter referred to as dose sheet) is a form generated by the CT scanner that displays important information about a CT examination. This sheet is also referred to as a dose summary page or patient protocol page in different literature and clinical settings.
This article discusses CT radiation dose, the measurement of CT dose, and CT image quality. The most commonly used dose descriptor is CT dose index, which represents the dose to a location (e.g., depth) in a scanned volume from a complete series of slices.
22 Μαρ 2013 · The absorbed radiation dose is the amount of energy absorbed per unit mass at a specific point and is measured in grays (1 Gy = 1 J/kg). The effective dose is a weighted average of the doses to all exposed organs taking into account varying organ radiosensitivities of different organs.
